Fun Fact Friday: Qualifications and Importance of Certified Welding Inspectors

By September 27, 2019No Comments3 min read

A certified welding inspector must have a combination of qualifying education and work experience, with documentation to support. According to the American Welding Society, to become a Certified Welding Inspector (CWI), an individual must have both adequate education and sufficient experience. Various levels of education are interchangeable with some years of experience, but by requiring a combination, the certification process ensures that a welder has the knowledge and capability to provide services without fail.

An individual meeting the education and experience criteria is able to apply for and take a Certified Welding Inspector exam. The application must be mailed at least six weeks before taking the exam, and many candidates choose to complete welding inspector training courses to help them prepare for and pass the exam. The exam itself is divided into 3 parts: fundamental knowledge, practical evaluation, and codebook navigation.

The fundamental knowledge section of the exam includes information on various welding processes, heat control & metallurgy, weld examination, welding performance, terminology, relevant welding and non-destructive examination (NDE) symbols, NDE methods, documentation, safety, destructive testing, cutting, brazing and soldering. Succeeding in this section of the exam proves that a welding inspector has the necessary levels of knowledge.

The exam also includes a practical evaluation section, where a welding inspector must demonstrate skill in procedure and welding, mechanical testing and determining properties, welding inspection and determining flaws, non-destructive examination, and utilization of drawings and specifications.

The third and final section of the exam, codebook navigation and applications, is exactly as it sounds. In this section a potential welding inspector must prove their ability to navigate various code books and apply the various codes as required by a project. This skill is critical to ensuring that welding inspections will be completed in compliance with regulations and will be able to adequately ensure the safety of people in the vicinity of the equipment having been welded.

Additionally, anyone seeking a certification must pass a vision test, to ensure they are able to adequately visually inspect welds.

Becoming a Certified Welding Inspector is a complex and challenging process, but this ensures that welding inspection services are provided to a high standard of quality.
